Jennifer Hull, 34, was at home with her two daughters, Hollis, 1, and Hatilynn, 4, who were in the children's playroom eating their snacks - veggie chips and bananas. A heart-stopping moment caught on the family's nanny cam shows the Texas mom saving her 1-year-old daughter from choking. She says she knew something was wrong when she heard a noise and her daughter started running toward her. That's when Hull sprang into action, picked up Hollis and starting giving her back blows.
